TRAVELING-FLAT CARDINGr-MACHINE.

Specification of Letters Patent.

Patented Mar. 18, 1919.

Application filed September 6, 1917. Serial N 0. 189,930.

To all whom it may concern:

Be it known that I, CHESTER C. LAMB, a citizen of the United States, residing at W'hitinsville, in the county of Worcester and Commonwealth of Massachusetts, have of carding the working flats are supported at their ends on flexible bends concentric with the carding cylind'er and'slowly move thereon due to motion transmitted by the connecting chains which receive their motion through connections with the cylinder. After passing over the carding cylinder the flats return to their working position over a number of revolving carriers Supported in stands fastened to the cylinder arch. After continuous usage the chains become slack due to the wear resulting between the chain link connections. Unless this slackness of the chains is taken up much damage is often done to the clothing on the flats due to the saggin of the line of flats against the adj acent cy inder casings.

The invention consists in the construction, combination, and arrangement of parts and details, as hereinafter described, and pointed out particularly in the claim.

Reference is to. be had to the accompanying drawings, forming part of this specification, in which similar numbers of reference indicate corresponding parts in all figures.

Figure 1 is a side elevation of a carding machine in part provided with my improved device for taking up the slack in the flat chain. Fig. 2 in an enlarged side view of the take-up device and its holding stand showing in full and dotted lines the different positions of the carrier supporting the flats. Fig. 3 is an enlarged sectional view on line X Y of Fig. 2 showing the relation of my improved device to the adjacent parts of the carding machine. It is understood that each cardlng machine has a chain slack take-up device applied on each side of the machine.

In the said figures, 1 is the card side leg, 2 is the cylinder revolving on itsshaft 3 in bearing 4 bolted to the card leg. Adjustably mounted on the arch 5 is the flexible bend 6 on the upper surface of which a series of-flats 7 connected together by the endless chain slide while in workin relation with the clothing on the cylinder. This chain as usually constructed consists of fiat steel links swivelly connected together by 1 pins or studs 9 screwed into the ends of the flats thus serving as holders for the same and maintaining them a proper distance apart.

After leaving their working position onthe cylinder the line of flats is drawn again to their working position by thecha-in over four-carriers 10, 11, 12, and 13 rotating on bearings supported by stand 14:, 15 16 and 17 respectively bolted to the card arch 5.

In course of time, after considerable usage, the chain becomes slack due to wearing of the chain link joints. This results in a sagging in the train of flats especially noticeable at the points of advancing to and leaving the working position on the cylinder.

f this slackness is not taken up there is a tendency for the flats to drop away from the end supporting carriers 10 and 13 and thus to be drawn into contact with the edges of the cylinder casings 18 and 19 thus causing considerable damage to the clothing on the flats. It is customary in the present construction of carding machines to employ an adjustable stand for supporting the flat carrier such as the stand supporting the carrier C shown in Fig. 1 of Patent No. 597 ,314, Jan. 11, 1898. By this construction the take-up of the chain slack is accomplished to a limited extent, when more is required the chain is shortened by removing one or more flats, this procedure necessitating considerable extra work for the operatives and also a loss in the productive capacity of the machine due to the necessary stoppage of the machine.

My invention overcomes these disadvantages by making use of the extension stand 20 with two adjusting slots and slidably connected to the bracket 15 bolted to the cylinder arch 5. The circular carrier 11 rotates onthe journal 21 integral with the holder stand 22 which is adjustably and sli'dably mounted on the stand and is held in a fixed relation theretoby'the bolt 23 and-"nut 24 clamping them together. The position of the carrier can be varied on the extension stand by means of the adjusting slot 25 through which the bolt 23 passes. The extension stand 20 is raised and lowered with reference-to thebracket 15 by the adjusting screw 26 and is fixed in any desired position 1 by the bolt 27 passing through the slot 28 and screwin intovthe boss 29 on the upper part of brac ret 15.

In operation of a carding machine When the flat chains are new the flat carrier 11 is.

' set with its holding bolt 23 in the bottom of the extension slot 25 and the adjusting stand 20 is set at'its lowest position onthe bracket 15 so that the holding screw 27 is at the top of the slot 28. As the chain stretches the operative takes up the slack.- ness by means of the adjusting screw 26 until the full length of the slot 28 is reached,, then if, further slackness appears in the chain it may be taken up as follows: block up the carrier 11 so that it and the flats supported thereon are maintained in position Without depending for support on the prising a driving shaft having a carding cylinder thereon traveling flats, a chain connecting the traveling fiats;. power transmitting means between the driving shaft and the chain, a cylinder. arch, a, flexible bend adjust-ably mountedv on: the arch, circular carriers supporting the returning line of flats, supportingstandslfor the carriers, one of the carriers mounted on ajournal integral with a, holding standslidably adjustable on an extension stand, said extension stand.

being slidably-mounted on a bracket fixed to the card. arch. V
